CHURN-MOTOR.

SPECIFICATION forming part of Letters Patent No. 236,964, dated January25, 1881.

To all whom it may concern:

Be it knownthat I, J B J. SMITH, of Frankfort, in the county of Franklinand State of Kentucky, haveinvented certain new and useful Improvementsin Uhuru-Motors; and I do hereby declare that the following is a full,

- clear, and exactdescription of the invention,

which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

Figure l is a perspective View, and Fig. 2 is a Vertical longitudinalsectional view.

Similar letters of reference indicate corresponding parts in bothfigures.

This invention relates to churn-motors; and it consists in certainimprovements in the construction of the same, ,which will be hereinafterfully described, and particularly pointed out in the claims.

In. the drawings hereto annexed, A represents an upright xed in a base,B, and carrying a longitudinal top or cross piece, C. The latter isprovided at itsrear end with a slot, D, to accommodate the pitman E,which latter connects a crank, F, upon a shaft, G, journaledtransversely upon the top piece, with the end of a treadle, H, suitablymounted upon the base. The shaft G carries at one end a ilywheel, I, andat the other end a disk, J.

The front end of the top piece, C, is provided with a horizontal slot,K, in which is mounted, upon a vertical pin or axle, a wheel or disk, L,provided with a laterally-extending arm, M.

N is a short arm or connecting-piece pivoted lto arm M, and connected bya hingejoint, O,

to a rod, P, the other end of which is pivoted upon the face of the diskJ. The rotary motion of the latter islthus, it will be seen, convertedinto an oscillating motion, which is con` veyed to the horizontal wheelor disk L.

Disk L is provided upon diametrically opposite sides with horizontal orsemi-annular grooves Q R, one of which is near the upper and theothernear the lower edge of the disk. At its rear end, or just betweenthe rear termination of the grooves Q It, the disk is provided with anotch, S. in which are secured two hooks orbuttons, T T, which, bymaking the notch sufficiently large, are readily accessible.

U U are belts or bands provided with holes Application led December 16,1880. (No model.)

or slots, by which they may be adjusted upon the hooks or buttons, fromwhence they pass around the sides of the disk, being adjusted in thegrooves Q It and to the front end of the top piece, (l. The latter isprovided with a suitable bearing for the vertical dasher-shaft V, whichis provided with a drum, W, around which the belts U are wound inopposite directions, and to which they are permanently attached.

The d'asher X. may be of any suitableJ construction. From the foregoingdescription, taken in connection with the drawings hereto annexed, theoperation and advantages of my invention will be readily understood. Themechanism, which is worked by foot-power, imparts to the dasher anoscillating motion, which is conceded to be very desirable. To removethe dasher, which it is necessary to do when the churn is to be placedin position or removed, it is only necessary to unbutton the belts U,which it is manifestly easy to do. The general construction of myimproved churn-motor is simple and inexpensive, and it is easilyoperated.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. As an improvement inchurn-motors, the combination of the upright A, having crosspiece C,crank-shaft F G, pitman E, treadle H, wheel or disk J, horizontal diskL, having arm M, pivoted connecting-piece N, con nectin g-rod I?, andmeans for conveying motion from the disk L to the dasher, substantiallyas and for the purpose herein set forth.

2. The combination of the dashershaft V, having drum W, belts or bands UU, secured to said drum and wound in opposite directions around thesame, horizontal disk L, having grooves Q R, notch S, and vhooks orbuttons T T,and mechanism for imparting to the disk L an oscillatingmotion, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto afxed mysignature in presence of' two witnesses.

JOB J. SMITH.
